Description

Technical Field

[0001] This utility model relates to the technical field of floor decking, and in particular to a prefabricated steel structure truss floor decking. Background Technology

[0002] Prefabricated construction is a modern construction method in which building components are prefabricated in a factory and then transported to the construction site for assembly. Among them, prefabricated truss floor decking is a key component of the building floor system, and its design and performance directly affect the construction efficiency and quality of the entire building.

[0003] Steel truss floor decking is made by welding the steel bars in the floor slab into steel trusses, which are then welded to a base membrane or fixed to the base membrane with wire to form a single, integrated floor decking. This process is cumbersome and inefficient. Therefore, a snap-fit ​​fixing structure was designed. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated steel structure truss floor deck to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A prefabricated steel truss floor deck includes: a steel truss on top of a base membrane; a fixing assembly on top of the base membrane, the fixing assembly including: a base plate fixedly disposed on top of the base membrane; a spring disposed inside the base plate; a locking block inserted into the interior of the base plate and connected to the spring; an arc-shaped rod disposed on top of the base plate, with one end rotatably connected to the base plate; and a slot formed on the inner sidewall of one end of the arc-shaped rod.

[0007] In some embodiments, one end of the arc-shaped rod has an arc-shaped bottom design.

[0008] In some embodiments, the fixing component further includes: one end of a pull rod passing through the base plate and inserted into the interior of the spring to be fixedly connected to the locking block.

[0009] In some embodiments, the fixing component further includes a pull plate fixedly disposed at one end of the pull rod.

[0011] In some embodiments, a limiting component is provided on the arc-shaped rod, the limiting component further comprising: one end of a bolt passing through the arc-shaped rod and threadedly connected to the arc-shaped rod; and a push block rotatably disposed at one end of the bolt.

[0012] In some embodiments, one side of the pusher block has an arc-shaped design.

[0013] In some embodiments, the limiting component further includes: convex plates symmetrically fixedly disposed on both sides of the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The floor decking uses a fixing component that engages with a clip and a slot to secure the curved rod, allowing the curved rod to cover the reinforcing ribs at the bottom of the steel truss inside. This allows the steel truss to be installed on top of the bottom membrane, making the operation more convenient compared to existing welding or wire-tying methods. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] Currently, in existing technologies, steel truss floor decking involves welding the reinforcing bars in the floor slab into steel trusses, which are then welded to a base membrane or fixed to the base membrane with wire to form a single, integrated floor deck. This process is cumbersome and inefficient.

[0026] As shown in the attached drawings, this utility model embodiment provides a prefabricated steel structure truss floor deck.

[0027] The device includes: a steel truss 12 on the top of the base membrane 11; a fixing component 2 on the top of the base membrane 11, the fixing component 2 including: a base plate 21 fixedly disposed on the top of the base membrane 11; a spring 22 disposed inside the base plate 21; a locking block 23 with one end inserted into the interior of the base plate 21 and connected to the spring 22; an arc-shaped rod 24 disposed on the top of the base plate 21 and rotatably connected to the base plate 21 with one end; and a slot 25 formed on the inner side wall of one end of the arc-shaped rod 24.

[0028] Specifically, when the bottom membrane 11 is poured, the bottom plate 21 is placed on top of the bottom membrane 11, and the steel bars at the bottom of the bottom plate 21 are inserted into the bottom membrane 11. After the bottom membrane 11 solidifies, the bottom plate 21 can be fixed to the top of the bottom membrane 11.

[0029] In use, first place the reinforcing ribs at the bottom of the steel truss 12 on the top of the base plate 21. Then, simply rotate the arc rod 24 so that one end of the arc rod 24 rotates in a circular motion, enclosing the bottom end of the steel truss 12. When rotating, the other end of the arc rod 24 contacts the locking block 23 and presses the locking block 23. Because the locking block 23 is designed with a slope, when the arc rod 24 rotates and presses the locking block 23, the locking block 23 retracts into the interior of the base plate 21 and simultaneously compresses the spring 22 until one end of the locking block 23 is aligned with the locking groove 25. Then, the spring 22 rebounds and pushes one end of the locking block 23 into the interior of the locking groove 25, fixing the position of the arc rod 24. At the same time, the arc rod 24 restricts the bottom end of the steel truss 12 to the top of the base membrane 11, completing the installation of the steel truss 12 (after installation, the steel truss 12 is not fixed and will have a certain range of shaking, but this will not affect the pouring of concrete).

[0030] In some embodiments, the bottom of one end of the arc-shaped rod 24 is designed to be arc-shaped.

[0031] The arc design is specifically reflected in the fact that the corner of one end of the arc rod 24 is rounded, which can reduce the scraping of the locking block 23 when it makes contact with the inclined surface of the locking block 23.

[0032] In some embodiments, the fixing component 2 further includes: one end of a pull rod 26 passes through the base plate 21, is inserted into the interior of the spring 22, and is fixedly connected to the locking block 23.

[0033] The design of the tie rod 26 makes it easy to disassemble when replacing the steel truss 12. Simply pull the tie rod 26 to retract the locking block 23 and disengage it from the locking groove 25 to release the restriction on the arc rod 24 and disassemble the steel truss 12.

[0034] In some embodiments, the fixing component 2 further includes a pull plate 27 fixedly disposed at one end of the pull rod 26.

[0035] The design of the pull plate 27 makes it easy to grip and prevents slippage when pulling the lever 26.

[0036] In some embodiments, the fixing component 2 further includes a ring 28 fixedly sleeved on the outer side wall of the steel truss 12.

[0037] The design of the ring body 28 allows the arc rod 24 to be fixedly installed, so that the arc rod 24 at the interval between the two ring bodies 28 can further limit the swaying of the steel truss 12.

[0038] In some embodiments, a limiting component 3 is provided on the arc-shaped rod 24, the limiting component 3 further comprising: one end of a bolt 31 passing through the arc-shaped rod 24 and threadedly connected to the arc-shaped rod 24; and a push block 32 rotatably disposed at one end of the bolt 31.

[0039] After installation, simply grip the bolt 31 and rotate it. As it rotates, push the push block 32 to move, so that the push block 32 fits against the bottom reinforcing bar of the steel truss 12, thereby further restricting the reinforcing bar.

[0040] In some embodiments, one side of the pusher block 32 has an arc-shaped design.

[0041] The curved design allows for a better fit when in contact with the reinforcing ribs.

[0042] In some embodiments, the limiting component 3 further includes: protruding plates 33 symmetrically fixedly disposed on both sides of the base plate 21.

[0043] The design of the convex plate 33 can restrict the rotation of the push block 32, allowing it to move stably.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
